MTS Multipurpose Elite - Manual (Page 219)

Syntax
Polynomial(X,Coefficients)
Unit Class
The units associated with the Y data used to calculated the coefficients.
Example
Polynomial(X, coefficients)
This example returns the Y value calculated at the value X.
PolynomialFit
The PolynomialFit function fits a polynomial curve of the specified order to the data arrays.
Returns
The coefficients as an array. The number of array values returned is one plus the order specified.
Syntax
PolynomialFit(yArray, xArray, Order[, StartIndex, EndIndex, rSquared])
Parameters
yArray - The Y array data being analyzed.
xArray - The X array data being analyzed.
Order - The order of the polynomial fit.
StartIndex - The optional start index of the region to be analyzed.
EndIndex - The optional end index of the region to be analyzed.
rSquared - An optional variable that is used to pass the coefficient of determination (R2)
Unit Class
Dependent on the coefficient.
Example
PolynomialFit(Force, Extension, 1, Slope1, Slope2)
This example returns the coefficients for a straight line through the regions specified by Slope1 and Slope2.
